The miniz is used for zlib compression. But because that library has some bugs related to a smal window sizes (we need 4096), I had to make some patches to the library. The miniz library happens to also be part of esp-idf. To distinguish between our version and the esp-idf version, I created a `namespace Miniz` around our version. But nevertheless, the esp-idf version is called when I'm calling Miniz::tdefl_init and Miniz::tdefl_compress . Why??
Anyway, renamed tdefl_init and tdefl_compress to tdefl_initOEPL and tdefl_compressOEPL to get it working. This is ugly. If somebody has a better solution, please let me know!
- added webinterface for tag flasher
- added tcp transport for communicating with tag flasher (OTG USB also still works)
- added content 'timestamp', makes use of preloaded images and buttons on the 2.9" M3
- webinterface is now aware of C6 and flasher capabilities
- AP can run without ieee801.15.4 radio (i.e. flasher only) by shorting FLASHER_AP_TXD and FLASHER_AP_RXD
- added tcp transport option to OEPL-Flasher.py (serial also still works)
- added new environment OpenEPaperLink_Mini_AP_v4
- lots of finetuning and bug fixes
Pretty complex change here: pending images/commands are now queued.
A command (like LED flasher) will not overwrite a pending image anymore. Also, sending multiple preloaded images is possible.
Also works (at least, as far as I could test) in combination with Multi AP and mirroring tags ('display a copy' content type).
It you want to test this: don't forget to upload the changed files in /www (the pending icon is now displaying the amount of queued messages). Timing improvements will follow later (only one message can be transmitted every checkin. If multiple messages are queued, at this moment, you have to wait until the next checkin which takes 40-60 sec).
This comes also with the advantage of better stability if you upload multiple images to the same tag in succession. Before queuing, if was possible to replace the image between sending the pending message and the image transfer to the tag, causing md5 mismatches and instability.
Solves #47
- added short date format definition in language.json
- changed english date format to mm/dd
- added lightgrey (4)/darkgrey (5)/pink (6) colors in jsontemplate (uses pattern dither)
- fixed ntp init timing
- got rid of gamma correction during dithering for quality reasons
- smaller UI improvements and textual edits
- tag grouping in the interface is now sticky across sessions
- tag auto update now shows before/after version number
- neopixel idle color now represents AP status
- option to invert colors (advanced options at tag card)
- filename dropdown in tag card when a filename is expected
- redrawing pending instead of raw, if previews are off and tag reboots
- tft brightness setting independent from neopixel brightness
- Wifi connection progress is now visible on the TFT
- passthrough serial logging from the C6 to the S3 terminal for easier debugging
- no checks on force_flash and APtag-firmware version when C6 is used
- AP info screen content card. Can run on any tag.
- now, you can use {variables} in the 'text' entries in a json template. You can set variables via a http call. If you update a variable, all tags with a json template containing that variable get updated.
- font name in json template is more flexible. You can just use 'filename.ttf' or 'filename.vlw'. A full path is still possible.
- colors in the json template can now be set using #rrggbb color values, and using 'black', 'white' or 'red'.
- added direct output for the TFT display for the yellow esp32-s3. No file writes needed.
- added POST variable 'ttl' to json template upload and image upload, to set the next checkin time
- added /variables-demo.html to demonstrate the variables.
- json templates received from jsonupload are now saved in /current, and reused.
- known issue: 'backup db' button doesn't work due to some browser policy change. Fixing.
thanks to @steinwedel for the inspiration on the variables and some other fixes.
- new: tagtypes are be defined via json in /tagtypes instead of hardcoded
- content template is moved to the tagtype definition
- optimalisation of spr2buffer (also uses psram now, if available)
- bugfixes in spiffseditor
- size fix in painter screen for large screens
This one saves a lot of flash space.
Now, wifimanager is replaced with our own method for managing the wifi connections.
Also, the whole thing will run now even if there is no wifi. If wifi disappears, it automatically tries to reconnect in the background every few minutes.
Wifi settings now available at all times at /setup
If it cannot connect, an access point 'OpenEPaperLink' is created where you can set the wifi credentials (http://192.168.4.1/setup).
Sprite rendering is the most heap hungry operation in during
content generation. This can lead to ESP panics as the exception
for the failing "new" is not handled.
To further half the required the memory we are doing it in two passes
for black and red independant. While this add a few ms to the rendering
the main time of the rendering is writing to the FS anyways so the overhead
neglectable after all.

To be able to store more images and never worry about running
out of storage again we are adding support of SDCards.
We are faced with two options:
1) Remove the LittleFS code
2) Allow for both FSs but increase the app partition as we run
out of space.
We have opted for 2 for two reasons:
1) Unformated SDCards can be initialized from the littleFS
2) If the SDCard and the flasher share the same SPI pins
the SDCard needs to be completely disconnected so there needs
to be a FS in that rare case.
Performance wise the SDCard is not slowing the system down.
Writing the AP db with 70 APs takes 2.5 seconds, on the SD
only 800ms. This however is SD and setup depending.
By default the SDCard is expected on pins 18,19,23 however this
is configurable via preprocessor defines.
Globally we replace LittleFS with a new pointer to the currently
used FS allowing for hotswapping where the FS pointer is not saved.
One case which is therefore not working is the SPIFSEditor which
copies the FS interally.
